 TOPIC -----------------------------------------------------------

 What are the memory addresses for mouse information on the Apple IIe and
 Apple IIGS?

 DISCUSSION -------------------------------------------------------

 Apple IIe/IIc
 -------------
 With the mouse card in slot four of the Apple IIe, locations are stored as
 follows:

 - low byte x   $047C

 - high byte x  $057C

 - low byte y   $04FC

 - high byte y  $05FC

 (This is different if the card is in a slot other than slot four.)

 More data on Apple IIe and IIc applications is on pages 196 through 198 and
 page 363 of the "Apple IIc Technical Reference Manual" from Addison-Wesley.


 Apple IIGS
